Transport Request Workflow Prefix

hi,

all my Workflows are working in DEV system,

i transported all my requests to QAS,

but in QAS the SWU3 under Maintain Prefix Numbers, its showing (X) Red,

i do not know when settings were done in DEV did it ask request for Maintain Prefix.

So now my prob is in QAS Maintain Prefix is Red (X), how do i solve my problem.
